Thermal Energy&Heat
Term | Definition |
---|---|
Temperature | a measure of the average kinetic energy of each particle within an object |
Fahrenheit scale | The temperature scale on which water freezes at 32 degrees and boils at 212 degrees |
Celsius scale | the temperature scale on which water freezes at zero and boils at 100 degrees |
Kelvin scale | the temperature scale on which zero is the temperature at which no more energy can be removed from matter (absolute zero) |
absolute zero | The temperature at which no more energy can be removed from matter |
heat | Thermal energy that is transferred from one substance to another. |
conduction | The transfer of heat between particles within a substance |
convection | the transfer of heat by the movement of currents within a fluid or gas |
radiation | the transfer of energy by electromagnetic waves |
conductor | A material that easily transfers heat between its particles, conducts heat well |
insulator | A material that does not easily transfer heat between its particles |
state | the three forms in which matter exists - solid, liquid, gas |
change of state | The physical change of matter from one state to another. |
melting | The change from the solid to the liquid form of matter |
melting point | The temperature at which a substance melts |
freezing | The change from the liquid to the solid form of matter |
freezing point | The temperature at which a substance freezes. |
vaporization | The change from the liquid to the gaseous form of matter |
evaporation | Vaporization that occurs on the surface of a liquid |
boiling point | The temperature at which a liquid substance boils |
condensation | The change from the gaseous to the liquid form of matter |
Energy | The ability of a system to do work |
Matter | Anything that has mass and takes up space |
